FEEDING MECHANISM FOR sEwme-uAonmEa Specification of Letters ratent. Application filed June 8, 1904. Serial No. 211,004.

Patented Sept; 29, 1914.

, To all whom .z't may concern Be itknown that LCHEs'rER. MCNEIL, a citizen of the United States, residing at Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Feeding Mechanisms for Sewing-Machines, of which the following is adescription, reference being had to the acinclined feed dog is used, a portion of which engages the fabric ahead of the needles, and crowds said fabric up toward the same, so that when the stitches havebeen placed in said fabric and it comes out from the machine, it will not be puckered. This inclined feed dog is pivoted to its support and adj ustable to vary the inclination. It has been found in ractice with said inclined feed dog that w ere it is squared off in front, and is tilted to such position that the forward end extends above the top of the throat plate, that the goods will catch against the edge and will not begin to feed properly.

' The object of the present invention is to provide a construction of inclined feed dog wherein thefront end of the feed dog will always be in proper cooperative relation to the fabric for all positions of adjustment of said feed dog.

The invention consists in the matters hereinafter described and referred to in the appended claims.

Inthe accompanying drawings, which illustrate the invention, Figure 1 is a perspective view of so much of avsewing machine as is necessary to an understanding of the invention; and Fig. 2 is a sectional view of the feed dog and adjusting device.

In these drawings, A represents the bed of the machine: B the needle bar; C the presser bar; D the presser foot; and E the clothplate. The feed dog a is pivoted to the feed bar 1, by a pivot bolt 2, and a rod 3 carried by the feed bar'has a ball joint connection 4, with said feed dog. By means nection with its support, and when rotated moyes longitudinally of the feed bar, .thus tilt ngthe feeddog. The feed dog is shown as mchned generally from front torear, but at the front end of the feeding surface proper, it is tapered or rounded, as at a, in order that when the goods are placed in the machine, they will not encounter the It will be understood that I do notwish,-

to be limited to the exact details shown herein.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A sewing machine including in combination, a cloth plate, a needle and a feeding mechanism comprisinga feed dog, adapted to engage the material in front of the needle, means for projecting said feed dog through the cloth plate to engage and feed the work, said feed dog having the forward end of its feeding surface inclined downwardly and forwardly relatively to the rearward portion of said surface and beneath the surface of the cloth plate, said inclined forward portion having feed teeth thereon, and means for adjusting the relative position of the feed dogand cloth plate.

2. A sewing machine including in combination, a cloth plate, a needle, and a feeding mechanism comprising a feed dog, adapted to engage the material in front of the needle, means for projecting said feed dog through the cloth plate to engage and feed the work, said feed dog having the main portion of its feeding surface inclined downwardly and rearwardly, and its front portion inclined downwardly and forwardly beneath the surface of the cloth plate, said inclined forward -portion having'feed teeth thereon.

3. A sewing machine including in combination, a cloth plate, a needle, and a feeding mechanism comprising a pivoted feed dog adapted to engage the material in front of the needle, means for tilting said dog, means for projecting the same through the throat plate to engage and feed the work, said feed dog havin the forward end of its feeding surface inc ined downwardly and forwardly relatively to the rearward ortion of said surface and beneath the sur ace of the cloth plate, whereby the feeding of the'fabric is. not impeded by the end of the feed dog in its various tilted positions.

4;. A sewing machine including in combination, a cloth plate, a needle, a feeding mechanism comprising a pivoted feed dog' adapted to engage the material in front of the needle, means for tilting said dog, means I for projecting the same through the throat plate to enga' e and feed the work, said feed dog having t e main portion of its feeding surface inclined downwardly and rearwardly, E

and its front portion inclined downwardly and forwardl beneath the surface of the cloth plate, w ereby the feeding of the fabric is not impeded by the end of the feed dog in its various tilted positions. a

5 A sewing machine including in combination, a cloth plate, aheedle, a feeding mechanism comprising a feed do' adapte to enga e the material in front of t e needle, means or Projecting. the feed dog throu h the cloth ate to engage and feed the wor said feed. og'having the main portion of its feeding surface inclined downwardl and rearwardly, and its frontportion inclined downwardly and forwardly beneath the surface of the cloth plate, said main portion and said front portion having teeth project ing outwardly at substantially the same angle tothe surface of the feed dog.

In testimony whereof I afiix my signature, in presence of two witnesses.
